Trees are a great friend of mankind. If there is no tree in the world, there will be no man on earth. They are the most useful and beautiful gifts of nature. They give us oxygen without which no man or animal can survive. They give us food and wood. They help in maintaining ecological balance. People are now cutting down trees on a large scale. This is causing deforestation and which seriously harms our environment. It is breaking the ecological balance which is causing environmental disasters. To prevent this, we have to create mass-consciousness among the people. We have to make the people assimilated the dire consequences of deforestation. We also have to let them know the good results of forestation. The media can play a great role in doing this. We have to stop deforestation anyhow otherwise we all will be perished. If there are no trees, the chain of order in nature will break down. No man can survive in a treeless world.
